Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm FinePix X100 and the Pentax K-3 II? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The physical size and weight of the Fujifilm X100 and the Pentax K-3 II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The K-3 II can be obtained in two different colors (black, silver), while the X100 is only available in black.

Compare X100 versus K-3 II top
Comparison X100 or K-3 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-3 II is notably larger (39 percent) than the Fujifilm X100. It is noteworthy in this context that the K-3 II is splash and dust-proof, while the X100 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100 has a lens built in, whereas the K-3 II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the X100 gets 300 shots out of its NP-95 battery, while the K-3 II can take 720 images on a single charge of its D-LI90 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the K-3 II is 2 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Fujifilm X100 and Pentax K-3 II sensor measures

Despite having a slightly smaller sensor, the K-3 II offers a higher resolution of 24.1 megapixels, compared with 12.2 MP of the X100. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.90μm versus 5.53μm for the X100). However, it should be noted that the K-3 II is much more recent (by 4 years and 7 months) than the X100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the K-3 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Pentax K-3 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-3 II for good quality output (200 dots per inch) amounts to 30.1 x 20 inches or 76.4 x 50.8 cm, for very good quality (250 dpi) 24.1 x 16 inches or 61.1 x 40.6 cm, and for excellent quality (300 dpi) 20.1 x 13.3 inches or 50.9 x 33.9 cm. The corresponding values for the Fujifilm X100 are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

Unlike the X100, the K-3 II has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Fujifilm FinePix X100 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Pentax K-3 II are ISO 100 to ISO 51200 (no boost).

X100 versus K-3 II MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the K-3 II has a markedly higher DXO score than the X100 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 1.2 EV in additional dynamic range, and 0.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the K-3 II provides a better video resolution than the X100. It can shoot movie footage at 1080/60i, while the Fujifilm is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X100 has an electronic viewfinder (1440k dots), while the K-3 II has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the K-3 II has a higher magnification than the one of the X100 (0.63x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Fujifilm X100, the Pentax K-3 II, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The X100 has one, while the K-3 II does not. While the built-in flash of the X100 is not very powerful, it can at times be useful as a fill-in light.

The Pentax K-3 II has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the X100 and the K-3 II write their files to SDXC cards. The K-3 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the X100 only has one slot. The K-3 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X100 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Fujifilm FinePix X100 and Pentax K-3 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-3 II has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The X100 does not feature such a mic input.

Studio photographers will appreciate that the Pentax K-3 II (unlike the X100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the K-3 II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the X100 and the K-3 II have been discontinued, but can regularly be found used on eBay. The X100 was replaced by the Fujifilm X100S, while the K-3 II was followed by the Pentax K-3 III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Pentax websites.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Fujifilm X100 or the Pentax K-3 II – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Fujifilm FinePix X100:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Ready to shoot: Comes with a built-in lens, while the K-3 II requires a separate lens.
  • More compact: Is smaller (126x75mm vs 131x100mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the K-3 II).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More heavily discounted: Has been available for much longer (launched in September 2010).

ilogo

Reasons to prefer the Pentax K-3 II:

  • More detail: Has more megapixels (24.1 vs 12.2MP), which boosts linear resolution by 40%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.2 EV of extra DR).
  • Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.63x vs 0.50x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 2.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 460k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (8.3 vs 5 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (720 versus 300) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 4 years and 7 months of technical progress since the X100 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the K-3 II is the clear winner of the contest (26 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

X100 07:26 K-3 II

How about other alternatives? Do the specifications of the Fujifilm X100 and the Pentax K-3 II place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the X100 or the K-3 II perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
